It may be worth a comment on the mdraid wiki where the script is shown that older disks might need a manual addition to set the timeouts, and how to check, maybe with some examples of models known to have this issue. How do SSDs behave on bad sectors? Are SSds subject to the same long delays, trying and retrying to read the sector from disk? Is this timeout a strong concern for SSDs? Would it be worth trying to get a patch to smartctl? (In other words, is it likely they'd accept a change in behavior in this area?)
